SELF-ADJUST-ING BEARING.

.Specification of Letters Patent. v Patented Aug. 15, 1911,

'Animation med'Aprn 12, 1910. serial No. 555,066.

To all whmn it may concern:

Be it known that we, WREX A. HnNnEnsox, WILLIAM C. Gimimvand ALoNzo M. (lumix, citizens of the United States, residing at Sa'ord, in the county of Graham and Territory of Arizona, have invented new and use- -ful Improvements in `SelfAdjusting Bear,-

ings, of which the following is a specification. t

This invention relates to a shaft bearing of the self-adjusting type so as to automatically compensatefor wear of the parts.

The invention has for one of its objects to improve and simplifyl the construction and operation of devices of this character so as to be comparatively simple and inexpensive to manufacture,reliable and etlicient in invention comprises the various novel fea--v tures of construction and arrangement of parts which will-be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention Figure 1 is a section of a bearing taken transversely to the axes of the-shaft. Fig. 2 is a plan view of the bearing.

Similar reference characters are employed to designate corresponding parts throughout the several views.

Referring to the drawing, 1 designates the base of a bearing which has a semi-circular seat 2 for theshaft 3, and on this base 1 is a ea p 4, which has a semi-circular recess 5, in which the. shaft its. The cap 4; rests on the upper ends ot helical compression springs which are held in vertical sockets 'l' in the base l. '.l`he cap is held against lateral disphu'emeutl by bolts or studs'S screwed into the. base at opposite sides of the scat 2, aud these studsextend through sleeves or -tubular members E) carried by thel cap. The upper ends olE the studs or i'uembers S are' provided with slotsI l() disposed adjacent the upper .ends of the tubular memberst), and in these slots are wedges 1l which have their bottom faces resting on the members 9. The i upper. inclined faces of the wedges bear against the upper end Walls of the slots 1() so that as the wedges are drawn longitudinally toward each other, they will act on the members 9 to ldepress the cap against the tension of the springs 6.' These wedges are constantly urged inwardly by a spring 12 extening transversely to the shaft and over the top of the cap. The ends of the spring pass through lugs 13 on the inner ends of the wedges, and behind the lugs are nuts 14 screwed on the ends of the spring so that by adjusting the nuts, the spring can be set to any desired tension. It will thus be seen that the spring forms a common devlce for constantly urging the wedges in such a direction as to cause the cap to press againstv the shaft and thus automatically compensate for the wear of the bearing parts as well as the shaft. The device can be readily taken apart for repair or inspection, andv the tenii sion on the cap can be adjustedwto a nicety.

From the foregoing description`V taken in connection with the accompanying drawing, the 'advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention relates, and while we have described the principle of operation of the in'- vention, together with the device which We now consider to be the best embodiment thereof, we desire to have it understood that the device shown is lnerely illustrative and that such changes may be made when desired as are within the scope of the claims.

l/Vhat we claim as new and desire to secure by Letters Patent is 1. A bearing comprising a fixed section, a Amovable section coperating therewith, a journal disposed'between the sections, fixed parallel members fastened to the fixed seotion and extendin through the movable section, said members being disposed at Opposite sides of the journal, wages extending transversely through the members andbearing on the movable section, said wedges tapering inwardly toward each other, and a helical extension spring extending transversely to the journal and approximately in a-linement with and between the wedges, and means for detachably and adjustably connecting theends'of the-spring with the respectiif'ewedges for exerting substantially the same inward pull on the wedges and 'buse section.

whereby ythe spring is' supported wholly by the latter.v

2. A bearing comprising a base section, a cap sectioinguide,members on the base see-` tion, tubular members on the cap section through which the guide members extend, wedges disposed b/etween the guide and tubuhir members, Iand a 00111111011 device acting 0n bothA wedges to yieldinglyfurge the Crip section toward the base section.

.3. A bearing e01i1prising a base section, n cap section, guide members on the base scetion, tubular members on the cup section through which the guide members extend, Wedg s disposed between the said members, and Hspring disposed'between thewvedges and adjustzibly connected therewith for siy multaneously moving the wedges in u direction to `urge theorie-section toward the 4. A bearing comprising a' base section, a

cap section, guide members onthe base section, tubular members on the cap section through whieh the guide members extend, wedges disposed between the said members, 25

a sprmg disposed between the Wedges and 'adjustably connected therewith for simultaneously moving the wedges in o. direction to -urge the cap seet10n toward the base section, and yielding means between the basev 30 tures in presence of two witnesses.
